What have you done to your SLK32 to get that kind of hp and torque. I have 2005 Crossfire SRT6 and have changed pulleys and flashed computer. I am getting about 325 at wheels, you are getting quite a bit more. My best 1/4 is 12.74 at 111. I will say I have actually had the car to 173 and there's a YOUTUBE video where a guy shows 179mph, not km but mph. It's real video. Somewhere in this forum a really cool dude put together top speed per gear. In 5th gear, 3.07 ring gear and 6300rpm you theoretically could achieve 188mph.
